DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new particulate applicator attachment for a leaf blower embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

In use, the attachment 10 is designed for attachment to a blower tube of a leaf blower for applying particulates to an area, such as a yard or garden. As best illustrated in FIGS. 1 through 4, the particulate applicator attachment for a leaf blower 10 generally comprises an elongate main tube 12 having opposite intake and discharge ends 13,14. Each of the ends of the main tube 12 has an opening into the lumen of the main tube 12. The intake end 13 of the main tube 12 is adapted for attachment to a blower tube of a leaf blower such that the lumen of the main tube 12 is in fluid communication with the blower tube. A container 15 for holding particulates is coupled to the main tube 12. Provided in the lumen of the main tube 12 are intake and outlet conduits 16,17. One end 18,19 of each of the conduits is connected to the container 15 such that the lumen of the main tube 12 is in fluid communication with the interior of the container 15 through the conduits.

In closer detail, the elongate main tube 12 is generally cylindrical and has a longitudinal axis, a lumen and opposite intake and discharge ends 13,14. Each of the ends of the main tube 12 has a generally circular opening into the lumen of the main tube 12. The intake end 13 of the main tube 12 is adapted for attachment to a blower tube of a leaf blower such that the lumen of the main tube 12 is in fluid communication with the blower tube. Ideally, the intake end 13 of the main tube 12 is designed for insertion into the nozzle end of a blower tube of a leaf blower. The intake end 13 of the main tube 12 is designed for receiving air blown out of the blower tube of a leaf blower while the discharge end 14 of the main tube 12 is designed for permitting discharge of air therefrom. In an ideal illustrative embodiment, the main tube 12 has a length of about 10 inches and a diameter of about 4 inches.

A generally disk-shaped container 15 is coupled to the main tube 12. The container has an interior for holding particulates such as powdered pesticides therein. Intake and outlet conduits 16,17 are disposed in the lumen of the main tube 12 between the ends of the main tube 12. Preferably, the intake and outlet conduits 16,17 are positioned adjacent to one another and located in a support post 26 extending across the diameter of the lumen of the main tube 12. Each conduit is preferably generally L-shaped and has a pair of open ends. One end 18,19 of each of the conduits is connected to the container 15 such that the lumen of the main tube 12 is in fluid communication with the interior of the container 15 through the conduits. As illustrated in FIG. 3, the other end 20 of the intake conduit 16 faces towards the intake end 13 of the main tube 12 such that air moving from the intake end 13 of the main tube 12 towards the discharge end 14 of the main tube 12 such that air passes through the intake conduit 16 into the interior of the container 15 so that the passing air may mix with particulates held in the interior of the container 15. The other end 21 of the outlet conduit 17 faces towards the discharge end 14 of the main tube 12 such that the mixture of moving air and particulates in the interior of the container 15 may pass into the lumen of the main tube 12 and out of the discharge end 14 of the main tube 12 to be applied to a yard or garden. Ideally, the other ends 20,21 of the conduits 16,17 are centered in the lumen of the main tube 12 along the longitudinal axis of the main tube 12.

Preferably, the main tube 12 has a secondary outlet tube 22 outwardly extending therefrom to form a secondary outlet opening 23 into the lumen of the main tube 12. The secondary outlet tube 22 is positioned between the intake end 13 of the main tube 12 and the intake conduit 16. The secondary outlet tube 22 has a longitudinal axis which is extended at an acute angle from the longitudinal axis of the main tube 12 with respect to the discharge end 14 of the main tube 12. A generally disk-shaped deflector plate 24 is provided in the lumen of the main tube 12. The deflector plate 24 permits a user to control the amount of particulate sprayed from the discharge end 14 of the main tube 12. The deflector plate 24 is positioned between the intake end 13 of the main tube 12 and the intake conduit 16. The deflector plate 24 is pivotally mounted (or rotationally mounted) to the main tube 12 to permit pivoting (or rotation) of the deflector plate 24 about an axis substantially perpendicular to the longitudinal axis of the main tube 12. The deflector plate 24 preferably has a turning knob 25 outwardly extending from the main tube 12. The turning knob 25 is designed for permitting pivoting (or rotation) of the deflector plate 24 by a user turning the knob 25. The deflector plate 24 is designed for selectively deflecting air moving from the intake end 13 of the main tube 12 to the outlet end of the main tube 12 towards the secondary outlet tube 22 so that more or less air may be channeled away from the intake conduit 16 and discharge end 14 of the main tube 12 and towards the secondary outlet opening 23.

In use, the container is filled with powdered pesticides and the intake end of the main tube is attached to the blower tube of a leaf blower. Some of the air blown into the main tube from the leaf blower passes through the intake conduit into the interior of the container to mix with the particulates of the pesticide. The air and particulate mixture then passes back into the lumen of the main tuber through the outlet conduit and out through the discharge end of the main tube. To control the amount of particulates sprayed out of the discharge end, the deflecting plate is turned to deflect more or less air towards the secondary outlet opening to decrease or increase, respectfully, the amount of air and particulate mixture discharged from the discharge end of the main tube.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
